Mouse anti Rat CD4 (Domain 1) antibody, clone OX-38 recognizes the rat CD4 cell surface antigen, also known as W3/25 antigen or T-cell surface antigen T4/Leu-3. CD4 is a 430 amino acid ~55 kDa single pass type I transmembrane glycoprotein expressed by T helper cells, monocytes and macrophages.

Clone OX-38 competes for binding with Mouse anti Rat CD4 antibody, clone W3/25 (MCA55R).

Mouse anti Rat CD4 (Domain 1) antibody, clone OX-38 has been utilized successfully for the in vitro depletion of T helper cells from slice cultures in studies looking at myelin loss in multiple sclerosis, the observed disruption being abrogated in these experimental conditions by T-cell depletion (Pusic et al. 2015).
